If we're leaving feasibility out of the equation, I would much rather do away with money altogether and run on a barter system.
But we're not, so my curiosity would be how that would translate in areas with a lower cost of living. Is universal basic income going to account for the different costs of living by region/country? And if so is that going to be used to economically disadvantage those who live there? Or if it's too high, small businesses will be pushed out for larger corporations because they won't be able to pay employees. I would much rather see a revolution of people deciding where their money goes, and based off of that what small businesses can afford to pay their employees, while laws regarding base income apply to larger corporations that are above a certain capital net income. Otherwise we're inviting the government to manage us in one more way.
Instead of "pay us this amount all the time everywhere" and giving the state the ability to determine how much all businesses should be paying, it might be more effective to say "If a business is making x amount of net income, __% should be redirected to employees." That way if a business is small or failing, they won't go under simply for high employee wages that may not accurately correspond to the work/location, but businesses making above a certain amount of net money would have to send it back towards the workers.
